Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-4, a bamboo-plastic plywood with a seal comprises a plywood body 1 and a seal 2 arranged around the plywood body 1, wherein an adhesive layer 3 is arranged between the seal 2 and the plywood body 1.

In further detail, the adhesive layer 3 is a PUR hot melt adhesive layer, and the adhesive layer 3 is made of PUR hot melt adhesive.

More specifically, the width of the seal 2 is equal to the thickness of the plate body 1. The seal 2 is not higher than the plate body 1, and the seal 2 and the plate body 1 are flush, so that the overall attractiveness of the plate body 1 is improved.

More specifically, the length of the seal 2 is equal to the circumference of the four sides of the plate body 1. When using the machine to carry out the banding around board body 1, because the length of strip of paper used for sealing 2 is equal with the girth of the four sides of board body 1, so the machine can directly carry out the banding around board body 1 for final edging, the condition that can not appear not being sealed around board body 1.

More specifically, the plate body 1 includes a first side 4, a second side 5, a third side 6, and a fourth side 7, and the seal 2 includes a first seal portion 8 attached to the first side 4, a second seal portion 9 attached to the second side 5, a third seal portion 10 attached to the third side 6, and a fourth seal portion 11 attached to the fourth side 7.

More specifically, the first seal 8, the second seal 9, the third seal 10, and the fourth seal 11 are integrally molded. Strip of paper used for sealing 2 is not the sectional type paste around board body 1, but bending of integrated into one piece formula pastes around board body 1, carries out the banding than the sectional type, and integrated into one piece formula strip of paper used for sealing 2 carries out the banding, and the wear resistance of board body 1 after its banding is better, and durability is higher.

In more detail, the seal 2 is made of soft PVC. Strip of paper used for sealing 2 that soft PVC made adopts the laminating of PUR hot melt adhesive around the board body 1, improves the wear resistance of board body 1 to improved the holistic durability of the board body 1, can satisfy the high building templates that require high to durability, also be applicable to the brick layer board.

In further detail, the board body 1 comprises a core layer 12 and a surface layer 13, wherein the core layer 12 is made of one or any combination of a wood veneer, a bamboo curtain and bamboo and wood plastic, the surface layer 13 is positioned on two end surfaces of the core layer 12, and the surface layer 13 is made of a PVC thin plate sheet containing heavy calcium carbonate. The core layer 12 is made of a wood veneer or a bamboo curtain, and the surface layer 13 is made of a PVC thin plate containing heavy calcium carbonate, so that the wear resistance of the plate can be effectively improved. The core layer 12 and the surface layer 13 are glued together.

In more detail, the plate body 1 is provided with chamfers 14 at the periphery, the seal 2 is provided with a chamfer sealing part 15, and the chamfer sealing part 15 and the seal 2 are integrally formed. The chamfer 14 also needs to be sealed, so that the overall wear resistance of the plate body 1 is greatly improved, the chamfer 14 is sealed by the chamfer sealing part 15, and the chamfer sealing part 15 and the seal 2 are integrally formed. The adhesive layer 3 is also used to adhere the chamfer seal 15 and the chamfer 14. The seal 2 is subjected to tracking chamfering processing while being stuck so that the seal 2 does not rise above the surface of the plate body 1.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms of the plate body 1, the seal 2, the adhesive layer 3, the first side 4, the second side 5, the third side 6, the fourth side 7, the first seal portion 8, the second seal portion 9, the third seal portion 10, the fourth seal portion 11, the core layer 12, the face layer 13, the chamfer 14, the chamfer seal portion 15, etc. are used more herein, the possibility of using other terms is not excluded.
